HE-R Series Relays

Compact Size 4 Form A and 4 Form A 1 Form B 40A Power Relay for Energy Management Applications!

The Panasonic HE-R Series is an Energy Management Relay designed for 3-phase AC charging using its 4FormA contacts arrangement, which allows for the cut-off of all 3 phases plus neutral simultaneously. And the auxiliary contact is used to detect welding failures of the primary open contacts. The HE-R Series Relay also features a low coil-holding voltage for reduced power consumption and is PCB mounted to ease board assembly. This Relay also meets the necessary Short Circuit Current Rating (SCCR) to pass UL and IEC standards for EV charging equipment, making it suitable for charging stations, industrial equipment, and more.

Features / Benefits of the HE-R Series Relay

High Capacity Switching and Carry Current Capability
Mirror Contact Structure with Auxiliary Contact Allows For Welding Detection Function Compliant With IEC60947-4-1 Standard
Low Operating Power (0.49 Watts) Using Reduced Coil Holding Voltage
Short Circuit Current Rating (SCCR) Can withstand Peak Current of 1.85kA with I2t of 4.5kA2s (Compliant with IEC62955)
